a dear with a broken leg

there is a dear in my yard with a what looks like a broken leg its been there for a week. its not doing anything will it die or will it heal if i just leave it.

From the webmaster: If it is up walking around and can eat or leave if it wanted to, just leave it alone. If it is just lying there, call the local animal control. They will put it out of its pain before it starves.
